To all ifi/ifm?. 'it may mare/'1i Be it known that l, 'l'iiouis` rl`.Ciiaiaixrii, a citizen ot the lrnited States, and a resident of theeitlv of New York, borough ot .\l:ln hattan, in the eoiiiitv and Stateot' .Yew York5 have invented a new and liiipioved Automatic Train-Stop.of whieh the follow ing a full. eli-ar. and exaet deseription.

This invention relates to train stopsl and particularly to autou'iatietrain .stops adapted to be carried by the train and arranged to engageand aetuate danger arnis positioned along the traek whereby the stopmechanism will he operated l'or opening the air brake. system ot thetrain when the daiige* arms ha ve heen engaged.

A\uothei' olijeet iii view is the provision ot an overhead appliaiieewhieh is simple iu operation and adapted to he operated al aniiiiiuiiilii eost, the .saine being eapalile ol'.

use on traeksy iii the open and traeksl extend ing through tunnels. n

A still further ob'ieet iii view is to provide an aiitoiiiatie .stopstrueture designed to he attaehed to a loeoniotive or other part ol` thetrain provided with .-i sliding ai'ui and other iiieehauisiii assoeiatedtherewith wliereb)7 the arm ina v lie inoved so as to present. wlial ina\v he termed :i short aria when passing through a tunnel and againadjusted l'oi presenting au oi'iliuarv long arni when passing ou auordinary traek.

Fig. 2 is a view suiilar to Fig. lv. exeept that the ai'iii is shownextended for use outside ot' a tunnel.

Referring to the aeeonipauving di'a\\'ing hv nuiiieials. l iiidieate.`:i part ol the rah oll a loeomotive. #aine heilig olI :in v desired orpreferred .sliiu'tiirin .\f\soeiated with the eali l is a pipe 2l'orniiug part of the ail' lil-alte svsteni, wliirii pipe is 4suppliedwith a valve il. wherehi the air brake s vsteni iiiav be opened :it :inv linie. Valve ."i univ he of' :inv desired .sirio-lure :iiid isprel'eralilv provided with :iii upwfiidl)` extending shaft -l and ahandle 5, the handle being operable b v the engineer at any time forsetting the brakes or for closing the valve. The Shaft 4 has rigidly7eonneeted therewith a sleeve 6 which is provided with a clutch face 7designed to engage the clutch face 8 of sleeve 9, which last mentionedsleeve is rigidly secured b v any desired means, as for instance ke 10,to shaft l1, which shaft extends upwardlyv through the rotatable plate12 carried by the roof of the eab 1. The sleeve 6 is rigidly seeured tothe shaft 4 by any desired means, as tor instance a key. so that whenthe shaft 11 is rotated. as hereinafter fiillv described `sleeve 9 willbe rotated and will transmit motion to sleeve (l and from thence to shat't 4 and the valve 3 for opening said valve. The shaft ll extendslooselyv through the plate l2 which plate is rigidly mounted ou asuitable support 13 forming part of the root' ofthe eab. said platehaving a lslot 14 through which the rod 15 extends whereby the rod will'FreelyY operate and rotate willi the plate l2. Rod 15 is pivotiillyconnected to the other end b v a bell crank lever 1li. The long end otlbell Crank lever 1G is provided with a slot 17 through which the pin 1Sprojeets. said pin being rigidly serured in :in v desired manner to therod 19 slidnglv mounted on the arms 20 and 2i of llie lu'aeket 22.lii'aeket 22 is rigidly seeured to shaft l1 wherehv whenever the rodengages a stop Q3 in a tiiunel or a stop 24 outside ot' a tunliel shaft11 will be moved to a eertaiii extent and will open the valve Ilwhereupon the brakes will be applied. Ordinai'ilv along a railroad trackit` is desirable that the various posts and other proieetions shall bean appreciable distance troni the eab of the engine and the variousroarlies. but in a tunnel a limited spare only is provided. To allow thedanger stops ontside the tunnel to he spaeed an appreciable distaiirefrom the ti'aek the rod 19 is made slidahle so as to provide what mav hetermed a long arm as shown in Fig. 2 for outside work. and a vshort armas shown in Fig. 1 l'orinside or tunnel work. vhen in either positionthe :ietion is the same. namelv. a partial rotation ot' the shaft 1l andparts assoi-iated therewith for openingr the valve 3.

'hen the parts are in the position shown iii liig. 2 and theengine.approaehes a timiiel the engineer will pull downwardly upon therod 15 whereupon the bell erauk lever 16 will act on rod 19 for movingthe same to the position shown in Fig. l where it is in proper positionfor engaging stop 23, if said stop is set at danger'. After the tunnelhas been left rod 15 is pushed upwardly and the parts moved back to theposition shown in Fig. 2 so as to engage the arm 24 if set at danger.After the shaft 11 has been operated by rod 19 striking a danger arm,said rod and danger arm may be moved back to its former position in anydesired Way, as for instance by operating handle 25 or handle 5. In anyevent handle 5 must be moved back to close the valve in order to releasethe brakes. By reason of this construction and arrangement the brakesare automatically applied when passing a danger arm set at danger unlessthe engineer has arbitrarily operated handle 2b for moving the rod 19 toa position where it will not engage the danger arm. This is done where arelief train is entering a Section in which a wreck has occurred orwhere some relief is desired. In order to prevent any considerable shockto the device or the locomotive and also to prevent breakage rod 19 isprovided with a rubber bumper and also the danger arm is provided with arubber bumper so that the bumpers come together when rod 19 strikes thedanger arm. These resilient bumpers not only act to cushion the blow,but will )resent a removable structure whereby w ien they are worn moreor less new contact members may be provided instead of new rods and newdanger arms. In connection with the danger arms it will be of courseevident that they may be an ordinary semaphore now in common usepositioned to coact with the rod 19, or may be a special arm connectedwith the ordinary semaphore now in use, or connected with the semaphoresystem and operated simultaneously with the semahore.

What I claim is:

l. A device of the character described, an air brake valve, a shaftconnected With the air brake valve, a bracket having a pair of aperturedarms connected with said shaft, a sliding arm positioned in saidapertures,

and means for sliding said arm back and forth so as to provide a shortand long arm` 2. In a device of the character described, an air brakevalve, a shaft connected with the air brake valve through independentlymovable clutch faces, a bracket carried near the upper end of saidshaft, a horizontal slidable rod arranged in said bracket, a bell cranklever mounted on said bracket and connected with said rod for moving therod to an outer and inner position, and means extending from said bellcrank lever to a point accessible to the operator.

3. In a device of the character described, an air brake valve, a shaftconnected with the air brake valve, a reciprocating member connectedwith the upper part of the shaft, and means extending to a point nearthe air brake valve for reciprocating the reciprocating member.

4. In a device of the character described. an air brake valve, means formanually opening and closing said valve, a shaft, a clutch having one`member connected with said shaft and the other connected with said valvewhereby when the shaft rotates in one direction the valve will beopened, a bracket arranged at the upper end of the valve, a, horizontalsliding rod acting as an operat` ing arm arranged in said bracket, andmeans for shifting the position of said rod so as to act as a long or ashort rod whenever desired.

5. In a device of the character described, an air brake valve, a shaftconnected with Said valve, a rotatable plate carried by the shaftclosing the opening through which the shaft passes when the shaft isarranged on a cab, said plate having a slot, a bracket con-` nected withthe upper part of said shaft. a horizontal sliding rod arranged in saidbracket, a bell crank lever pivotally connected to said bracket andengaging said rod for shifting the position thereof so that the rod Willact as a long and short arm` and an operating rod connected with saidbell crank lever extending through the slot in said plate.
